This was our project this weekend. Neal and I found both these items at Waldo Antiques picked up the buffet for $165, I've seen these sold online anywhere from $300-$500.
jigsaw (which we rented for a couple hours)
1 can of spray paint for mesh and hardware
can of satin paint
small can of sealer
foam brushes (for sealer)
white wax candle
Step 1: Take off all hardware and Sand down entire piece, with a jigsaw cut out inner square of doors. Then wipe down with clean damp cloth.
Step 2: Run candle on sharp edges or anywhere you don't want the paint to adhere to.
Step 3: Paint entire piece and allow to dry for several hours. While you wait for it to dry lay out hardware and mesh piece and spray paint.
Step 4: Take light grit sand paper and rough up edges (antiquing it).
Step 5: Use the foam brush and apply a coat of sealer.
Step 6: Take mesh and staple it behind the opening and put hardware back on.
Here is the mirror I found and cleaned up and added a fresh coat of spray paint to.
